Question

What is the format of an IP address?

Answer 1

It is usually written as a series of four numbers between 0 and 255 (inclusive) separated by dots, e.g.:

209.73.187.220

You might see an IP address with the number of bits used for the subnet written after it with a slash, e.g.:

192.168.100.1/16

which is known as CIDR Notation.

Internally it is stored as a 32-bit binary number, much like anything else.

Answer 2

127.0.0.1

Local Host

4 numbers seperated by fullstops.

Answer 3

The first 3  blocks are a private company, the other numbers tell  the city, state, and how you connect to the web  

Answer 4

It's in binary code

Answer 5

An IP adddress is a 32 bit number - expressed as 4 octets in dotted decimal notation. The address is interpreted via a 32 bit mask which indicates the allocation of the bits as network (1) or host(0) address.

For example

   192.168.25.100 255.255.255.0

The first 3 octets of the mask are 1's - so the network is 192.168.25

The last octet of the mask is 0's - so this is host number 100

There are lots of web pages or books that you can read on IP addressing.
